[PATCH 07/15] bcache: use sysfs_match_string() instead of __sysfs_match_string()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx>

The arrays (of strings) that are passed to __sysfs_match_string() are
static, so use sysfs_match_string() which does an implicit ARRAY_SIZE()
over these arrays.

Functionally, this doesn't change anything.
The change is more cosmetic.

It only shrinks the static arrays by 1 byte each.
